Insect repellent and attractant compositions and methods for using same

ABSTRACT

Described is (i) a method of repelling Musca domestica L.(Diptera:Muscidae) or Aedes aegyptae for a finite period of time from a three-dimensional space inhabitable by Musca domnestica L.(Diptera:Muscidae) or Aedes aegyptae consisting essentially of the step of exposing a three-dimensional space to an effective Musca domestica L.(Diptera:Muscidae) or Aedes aegyptae-repelling concentration and quantity of a geraniol-containing composition consisting essentially of 50-100% of geraniol with the remainder of the composition being a compound selected from the group consisting of citronellol and nerol and (ii) a method of attracting Musca domestica L.(Diptera:Muscidae) or Aedes aegyptae using lavender absolute, benzoin, dimethyl benzyl carbinyl acetate, jasmine absolute, racemic borneol, d-limonene and/or dihydrolinalool. The attractants taken alone or in combination find utility primarily as bait enhancers for acute toxins and/or trapping devices. The above-stated attractants and repellents are described to be useful as such or contained in a polymer which can be a biodegradable polymer such as compositions containing a major proportion of poly(epsilon caprolactone) homopolymers.

This is a divisional of application Ser. No. 08/130,256, filed Oct. 1,1993, now U.S. Pat. No. 5,401,500, which, in turn, is a streamlinedivisional of U.S. Pat. Ser. No. Ser. No. 07/948,142 filed on Sep. 18,1992, now abandoned as originally filed.

BACKGROUND OF THE INVENTION

This invention relates to the use of geraniol-containing compositionsconsisting essentially of from 50-100% by weight of geraniol having thestructure: ##STR1## with the remainder of the composition being acompound selected from the group consisting of citronellol having thestructure: ##STR2## and nerol having the structure: ##STR3## asrepellents against house flies (Musca domestica L.(Diptera:Muscidae))and mosquitoes (Aedes aegyptae).

This invention also relates to the use of the compounds:

lavender absolute;

bezoin having the structure: ##STR4## dimethyl benzyl carbinyl acetatehaving the structure: ##STR5## jasmine absolute; racemic borneol havingthe structure: ##STR6## d-limonene having the structure: ##STR7## anddihydrolinalool having the structure: ##STR8## taken alone or takentogether as attractants for house flies (Musca domnesticaL.(Diptera:Muscidae)) and mosquitoes (Aedes aegyptae).

This invention also relates to the use of such compounds andcompositions of matter in insect repellents, soaps, insect traps and thelike wherein, the compositions of matter are used as such or incombination in control release systems with polymers such asbiodegradable polymers.

Unsaturated alcohols including 1-octen-4-ol and 1-nonen-3-ol are knownwith respect to controlling insects and 1-octen-4-ol and 1-nonen-3-olare disclosed to be so useful in repelling Musca domesticaL.(Diptera:Muscidae) and Aedes aegyptae in U.S. Pat. No. 4,764,367issued on Aug. 16, 1988 and U.S. Pat. No. 5,118,711 issued on Jun. 2,1992. Several unsaturated alcohols have been found to attract insectsand others have been found to repel such insects. Thus, U.S. Pat. No.4,152,442 issued on May 1, 1979 sets forth 6-nonen-1-ol in a compositionof matter used as an attractant for the male Mediterranean fruit fly.Chem.Abstracts, Volume 103, No. 71086p concerns the synthesis of(Z)-8-dodecen-1-ol land its acetate as pheromone components of theOriental Fruit Moth (Grapholita molesta). This is an abstract of thearticle in Acta Chem. Scan. Ser. B, 1985, B39(4), pages 267-72. U.S.Pat.

SUMMARY OF THE INVENTION

This invention relates to the use of geraniol-containing compositionswhich contain 50-100% by weight geraniol having the structure: ##STR24##and the remainder of the composition being a compound selected from thegroup consisting of citronellol having the structure: ##STR25## andnerol having the structure: ##STR26## as insect repellents against houseflies (Musca domestica L.(Diptera:Muscidae)) and mosquitoes (Aedesaegyptae).

This invention also relates to the use of one or more of the materials:

Lavender absolute, Benzoin having the structure: ##STR27## Dimethylbenzyl carbinyl acetate having the structure: ##STR28## Jasmineabsolute; Racemic borneol having the structure: ##STR29## d-limonenehaving the structure: ##STR30## and/or Dihydro linalool having thestructure: ##STR31## as attractants for house flies (Musca domesticaL.(Diptera:Muscidae)) and mosquitoes (Aedes aegyptae).

Our invention also relates to the use of the foregoing insect repellentcompositions in personal soap compositions, for example, the insectrepellent soap composition described in U.S. Pat. No. 4,707,496 issuedon Nov. 17, 1987, the specification for which is incorporated byreference herein. Thus, in applying the teachings of U.S. Pat. No.4,707,496 to our invention, a topical insect repellent soap compositionand a method of protection using such a composition is described wherethe insect repellent soap composition comprises:

(i) from 63.0 up to 99.5% by weight of a soap mixture containing from4.1 to 7% by weight of a soap of caprylic acid, from 3.8 to 7% of a soapof capric acid, from 32.1 to 45% of a soap of lauric acid, from 12 to17.5% by weight of a soap of myristic acid, from 5.0 up to 10% by weightof a soap of palmitic acid, from 1.6% to 3% by weight of a soap ofstearic acid, from 3.5 to 5% by weight of a soap of oleic acid and from0.9 to 5% by weight of a soap of linoleic acid;

(ii) from 0.1 up to 2% by weight of C₈ -C₁₈ is straight chain fattyacids.

(iii) from 10 up to 30% by weight of one of the geraniol-containingcompositions of our invention as set forth, supra, and

(iv) from 0.2 up to 5% by weight of an effective residual insecticide asdescribed in U.S. Pat. No. 4,707,496.

Other insect repellent soaps can be produced by adding ageraniol-containing composition of our invention to one or more of thecompositions described and claimed in U.S. Pat. No. 4,453,909 issued onJun. 12, 1984 and U.S. Pat. No. 4,438,010 the specifications for whichare incorporated by reference herein. Described in said U.S. Pat. No.4,453,909 and U.S. Pat. No. 4,438,010 is a process for making a tabletof saop containing a perfume containing core, hollow or solid fabricatedfrom a hard plastic material either thermosetting or thermoplastic. Thesoap from the resulting composite tablet is useable until the core iswashed clean and contains functional ingredients, e g., the repellentsdescribed, supra, and optionally, aromatizing agent until the core iswashed clean. This obviates the wastage of soap which normally occurs asa conventional soap tablet becomes very thin on use and at the same timegives rise to a continuously functional ingredient containing soap,(e.g., repellent and optionally aromatizing agent) tablet. Thus, thisinvention also relates to detergent bars having a plastic corecontaining a geraniol-containing composition and optionally, a perfume.More particularly, this invention relates to detergent bars intended forconventional toilet soap uses either as hand soaps or bath or showersoaps which are elastic or inelastic in nature but which contain a solidplastic core containing insect repellent and optionally perfume givingthem unique properties which alleviate wastage thereof and causes theenvironment surrounding the soap on use thereof to be both insectrepellent and optionally aromatized in an aesthetically pleasing manner.

Yet another aspect of our invention relates to the use of thegeraniol-containing repellents of our invention taken further incombination with N-(methyl toluyl)-methyl piperidines defined accordingto the structure: ##STR32## as described in U.S. Pat. No. 3,463,855issued on Aug. 26, 1969, the specification for which is incorporated byreference herein. The compounds defined according to the structure:##STR33## include: N-(meta-toluyl)-2-methylpiperidine;

N-(meta-toluyl)-3-methylpiperidine; and

N-(meta-toluyl)-4-methylpiperidine.

The proportions of compounds defined according to the structure:##STR34## to the geraniol-containing composition described, supra, arebetween about 1 part N-(meta-toluyl) methylpiperidine:99 partsgeraniol-containing composition of our invention down to 99 partsgeraniol-containing composition of our invention:1 partN-(meta-toluyl)-methylpiperidines.

In addition, the compositions useful in repelling insects of ourinvention can also contain 1-nonen-3-ol described and claimed in U.S.Pat. No. Nos. 4,693,890 and 4,759,228 issued on Jul. 26, 1988, thespecifications for which are incorporated by reference herein. The ratioof 1-nonen-3-ol:geraniol-containing composition of our invention usefulin repellent compositions may vary from about 1 part 1-nonen-3-ol:99parts geraniol-containing composition of our invention down to 99 parts1-nonen-3-ol:1 part geraniol-containing composition of our invention.

In addition to the soap fabrication, another aspect of our inventionrelates to the formation of repelling articles containing thegeraniol-containing compositions of our invention, that is, articlesuseful for repelling house flies (Musca domestica L.(Diptera:Muscidae))or mosquitoes (Aedes aegyptae) in combination with compatible polymerswhich may or may not be biodegradable (for example, high densitypolyethylene or low density polyethylene, or biodegradable polymers suchas biodegradable thermoplastic polyurethanes as disclosed in Japan KokkiTokyo Koho 92/13710 (abstracted at Chem.Abstracts Volume 116:236374q),biodegradable ethylene polymers having ester linkages in the main chainsuch as that disclosed by Japan Kokki Tokyo Koho 92/50224 (abstracted atChem.Abstracts Volume 116:236397z), biodegradable ethylene polymersdisclosed by Japan Kokki Tokyo Koho 92/50225 (abstracted atChem.Abstracts Volume 116:126398a) and poly(epsilon caprolactone)homopolymers and compositions containing same as disclosed in U.S. Pat.Nos. 4,496,467; 4,469,613 and 4,548,764 the specifications for which areincorporated herein by reference). Thus, another aspect of our inventionprovides a process for forming geraniol composition containing polymericparticles such as foamed polymeric pellets which include a relativelyhigh concentration of the geraniol-containing composition of ourinvention as defined, supra.

Thus, another aspect of our invention relates to the formation ofgeraniol-containing composition polymeric pellets by means ofintroduction into a single or twin screw extruder, in series, athermoplastic polymer followed by the geraniol-containing composition ofour invention which is compatible with the thermoplastic polymer, inturn, (optionally) followed by introduction of gaseous blowing agent orblowing agent which will produce a gas which is inert to the polymer andto the geraniol-containing composition previously introduced into theextruder.

The advantages of using a foamed polymeric particle are multiple, towit:

improved handling;

greater retention of the geraniol-containing composition when not inuse;

greater length of time during which the release of thegeraniol-containing composition of our invention from the polymer is at"steady state" or "0 order".

The nature of the extruder utilized in the process of our invention toform the geraniol-containing composition-containing polymer particles ofour invention may be either single screw or double screw. Thus, thetypes of extruder that can be used are disclosed at pages 246-267 and332-349 of the Modern Plastics Encylopedia, 1982-1983, published by theMcGraw-Hill Publishing Company, the disclosure of which is incorporatedby reference herein. More specifically, examples of extruders which areuseable in carrying out one of the processes of our invention (withmodification for introduction of the geraniol-containing compositions ofour invention) downstream from the introduction of the polymer and withfurther modification that the gaseous blowing agent is introduced stillfurther downstream from the point of introduction of thegeraniol-containing composition of our invention are as follows:

In producing the geraniol-containing composition-containing polymerparticles of our invention, various polymers may be utilized, forexample, low density polyethylene, high density polyethylene,polypropylene, the co-polymer of ethylene and vinyl acetate, andpolyvinyl chloride. More specifically, the polymers used in the practiceof our invention may be co-polymers of ethylene and a polar vinylmonomer selected from (a) vinyl acetate; (b) ethyl acrylate; (c) methylacrylate; (d) butyl acrylate and (e) acrylic acid including thehydrolyzed co-polymer of ethylene and vinyl acetate. Preferredco-polymers are ethylene/vinyl acetate with about 9 to 60% vinyl acetateand ethylene/ethyl acrylate with about 6 to 18% ethyl acrylate.

Resins of the type disclosed for use as co-polymers are commericallyavailable in the molding powder form; for example, ethylene vinylacetate co-polymers are marketed by the E. I. duPont Nemours Companyunder the tradename "ELVAX® and by the Arco Polymer Division under thetrademark "DYLAND® and by the Exxon Corporation of Linden, N.J. underthe trademark "DEXXON®. Ethylene/ethyl acrylate co-polymers are marketedby Union Carbide Corporation under the trademark "EEA RESIN®.

The polymer is added to the single screw or twin screw extruder at afeed rate in the range of from about 80 up to about 300 pounds per hourwhile maintaining the temperature of the screw extruder between about160° C. and about 240° C. If the polymer or co-polymer powder is addedto the extruder at a reference "barrel segment", then thegeraniol-containing composition of our invention is added to theextruder under pressure downstream from the retention point of thepolymer at one or more of "barrel segments" (S-2, S-3, S-5, S-6, S-7,S-8 or S-9)(referring to FIG. 9 briefly described, supra, and describedin detail, infra).

The proportion of geraniol-containing composition (taken furthertogether with other insect repelling materials, if desired) to resin canvary from small but effective amounts on the order of about 1% of theweight of the resin body up about 45% by weight of the resin body. Ingeneral, it is preferred to use between about 5% up to about 30% basedon the weight of the resin body of insect repellent composition of ourinvention. This is an optimum amount balancing the proportion of theinsect repellent composition of our invention against the time periodover which the article emits the insect repellent composition andagainst the tendency of the components of the insect repellentcomposition to oil out either individually or in combination. This"oiling out" is specifically avoided as a result of the use of thefoaming agent discussed, infra.

No. 4,496,467 are those having the structures:##STR35## and ##STR36## wherein n represents an integer of from about500 up to about 1200 with the proviso that the average "n" varies fromabout 600 up to about 800.

Downstream from the addition point of the geraniol-containingcomposition of our invention taken alone or taken together with otherinsect repellent agents and fragrance materials, optionally, the gaseousor liquid containing blowing agent may be added (e.g., at "barrelsegments" (S-5, S-6, S-7, S-8, S-9 or S-10) using the polymer addition"barrel segment" as a refrence "barrel segment" S-1. Examples of thegaseous blowing agents are carbon dioxide, nitrogen, mixtures ofnitrogen and carbon dioxide in proportions of from 1 up to 99% by volumenitrogen and from 99 down to 1% by volume carbon dioxide, helium,mixtures of helium and nitrogen, mixtures of helium and carbon dioxideand other gases which are inert at the temperature and pressure of thepolymer at the time of the extrusion operation. Thus, gas containingoxygen or other reactive gases, e.g., hydrogen, should be avoided. Thepressure of the gas blowing agent being added to the extruder at thepoint of addition may vary from about 80 to about 150 psig. Higherpressures may be used without adversely affecting the usefulness of thefoamed insect repellent composition-containing particle.

The feed rate range of insect repellent composition-containing but notlimited to the geraniol-containing compositions of our invention, may bebetween about 0.5% up to about 45% by weight of the polymer.

The dies of the extruder may create rod, sheet, film or ribbon. Theresulting product may then, if desired, be pelletized to form insectrepellent composition-containing polymer particles or the ribbon may beused "as is" as an insect repellent-containing polymeric article ofmanufacture itself.

In addition to the optional gaseous blowing agents (which arenecessarily "inert" gases), blowing agents may be added at the samepoint on the extruder which will create gaseous voids in the insectrepellent-containing polymer articles of our invention and these"blowing agents" are well known to one having ordinary skill in the art.Examples of such non-gaseous containing materials which yield gases onadmixture with the polymer in the extruder but which are still insert tothe insect repellent (or attractant as the case may be) are as follows:

(i) Under high pressure, ethylene, methane, propane, butane, propylene,methyl chloride, methyl bromide, vinyl chloride and methylene dichlorideas more specifically described in U.S. Pat. No. 2,387,730, thespecification for which is incorporated by reference herein;

No. 3,758,425,column 4, line 1-5, the specification for which is incorporated byreference herein;

(iii) Dichlorotetrafluoromethane, tetramethylmethane,monochlorodifluoromethane, dichlorodifluoro-methane, anddichlorotetrafluoromethane as described in U.S. Pat. No. Nos. 2,948,664and 2,948,665 issued on Aug. 9, 1990, the specification for which isincorporated by reference herein; and

(iv) Azo bis(formamide), diazoaminobenzene: N,N-dinitrosopentamethylenetetramine; N,N-dimethyl, N,N-dinitrosoterephthalamide;p,p'-oxy-bia(-benzen sulfonyl semicarbazide); aza bis-(isobutyronitrile)p,p'-oxy-bis(benzene sulfonyl hydrazide); p,p'-diphenyl-bis(sulfonylhydrazide); benzene-sulfonyl hydrazide; m-benzene-bis(sulfonylhydrazide) as more specifically described in U.S. Pat. No. No. 3,298,975issued on Jan. 17, 1967, the specification for which is incorporated byreference herein.

The resulting extruded (and, if desired, pelletized) material may thenbe, for example, injection molded to form a useful article. Suchinjection molding can be carried out in accordance with the procedure asset forth in U.S. Pat. No. 3,268,636 issued on Aug. 23, 1966, thespecification for which is incorporated by reference herein.

In addition, our invention relates to candle body materials which on useare both insect repellent and perfuming which contain thegeraniol-containing composition of our invention and, if desired, otherinsect repellent materials including, for example, at least one of thecompounds having the structure: ##STR37## in order to repel house flies(Musca domestica L.(Diptera:Muscidae)) and/or mosquitoes (Aedesaegyptae).

The house fly and mosquito-repellent-perfuming compositions which formpart of the candle body materials are within the followingspecifications:

(I) from 5 up to 100% by weight of an efficacious perfuming/insectrepellent composition containing the geraniol-containing composition ofour invention; and

(II) from 0 up to 95% by weight of a standard perfuming substance(non-insect repellent or insect repellent) which may include but is notlimited to:

1-nonen-3-ol;

1-octen-4-ol;

alpha-damascone;

beta-damascone;

delta-damascone;

trans,trans delta-damascone;

methyl jasmonate;

dihydromethyl jasmonate;

the schiff base of vanillin and methyl anthranilate;

the schiff base of ethyl vanillin and methyl anthranilate;

vanillin; and

ethyl vanillin.

The foregoing formula may require a solubilizing agent, e.g., the methylester of dihydroabietic acid (commerical name: HERCOLYN D®), benzylbenzoate, isopropyl myristate and/or C₁₂ -C₁₄ isoparaffin hydrocarbons.

The candle base composition can be standard paraffin wax, or it can betransparent or pastel shaded as more particularly described in U.S. Pat.No. 3,615,289 issued on Oct. 26, 1971 (the disclosure of which isincorporated by reference herein) and wherein the candle body comprisesas the basic components a mixture of:

(i) a thermoplastic polyamide resin formed from linoleic acidpolymerized with a polyamine compound;

(ii) an alkanol amide or alkanol amine; and

(iii) a stearic acid compound.

The weight ratio of candle body:insect repellent/perfumant substance orour invention may vary from about 0.8% up to about 10% with a range offrom about 0.8% up to about 2.0% being preferred when no non-insectrepelling perfume oil is used in conjunction with thegeraniol-containing composition of our invention; and with a range offrom about 1.5% up to about 10% by weight of the overall compositionbeing preferred when a non-insect repelling perfume oil is used inconjunction with the geraniol-containing composition of our invention.

Specifically, the polyamide may be a "VERSAMID® resin which is athermoplastic condensation product of polymerized linoleic acid withvarious polyamine compounds such as ethylene diamine, ethylene triamineand the like. Specific "VERSAMID® compounds are "VERSAMID® 900","VERSAMID® 930", "VERSAMID® 940", "VERSAMID® 948", "VERSAMID®950" and"VERSAMID® 1635". These compounds are products of the Henkel ChemicalCorporation of Minneapolis, Minn.

Another substance required in the clear candle composition consists ofabout 20-55% by weight of an alkanol amine or alkanol amide prepared bythe reaction of a fatty acide ester and amine whereby the ester and theamine are in substantially equal proportions, for example, compoundssuch as BARLOL® 12C2 (manufactured by the Baroid Chemical Company) amonoalkyl diethanolamine having 8 to 18% carbon atoms in the alkylchain. A third component of the clear plastic candle compositioncomprises one or more stearic acid esters or a mixture of stearic acidesters and stearic acid. These esters include such compounds asisopropyl isostearate, butyl stearate and hexadecyl stearate. Thesestearic acid compounds serve as stabilizing agents which permit theready incorporation of the insect repellent/perfumant compositions ofour invention up to a level of approximately 5% (total proportion ofperfume oil-insect repellent composition). They are carriers for theperfumant/insect repellent and may be used in a proportion of between 1and 50% by weight of the composition although the preferable range isbetween 20 to 30%. In this connection it is possible to use up to about10% by weight of a perfumant/insect repellent if part of the formula isreplaced by the material "NEVEX® 100", a product which is acoumarin-in-dene copolymer resin of very little unsaturationmanufactured by the Neville Chemical Company.

Rather than being a crystalline paraffin wax the candle base of ourinvention may be an oil gel that has as its base a light mineral oil, aninexpensive natural oil or a combination of such oils which oil gel hasa non-greasy surface and feel and sufficient rigidity to beself-supporting at room temperature. Such a gel is disclosed in U.S.Pat. No. 3,645,705 issued on Feb. 29, 1972, the disclosure of which isincorporated by reference herein. Such compositions of matter include:

(a) from about 35% up to about 85% by weight of an oil which is normallyliquid at room temperature chosen from the group consisting of lightmineral oils and natural oils having iodine values substantially withinthe range of 40-135;

(b) from about 7% up to about 40% by weight of a long chain polyamidehaving a molecular weight substantially within the range of 6000-9000and a softening point substantially within the range of 18° C.-48° C.;and

(c) from about 7% up to about 30% of an alcohol selected from the groupconsisting of 8 to 12 carbon primary alcohols.

Similarly, when used in insect traps, the attractants of our compositioncan be used in the same polymers as the repellents. Thus, for example,our invention contemplates one or a combination of the attractants (at alevel of from about 1% up to about 45% by weight of the polymercomposition):

lavender absolute;

benzoin having the structure: ##STR38## dimethyl benzyl carbinyl acetatehaving the structure: ##STR39## jasmine absolute; racemic borneol havingthe structure: ##STR40## d-limonene having the structure: ##STR41##dihydro linalool having the structure: ##STR42## imbedded in theinterstices of a microporous polymer which may be one of the polymers asset forth, supra.

Furthermore, the insect attractant-containing polymers of our inventionmay be insect attractant-containing biodegradable polymers as set forth,supra.

DETAILED DESCRIPTION OF THE DRAWINGS

The data set forth in FIGS. 1, 2, 3, 4, 5A, 5B, 5C, 6A, 6B, 7A, 7B, 8Aand 8B were determined using the olfactometer of FIG. 10 and the insecttrap of FIG. 21. Referring to the olfactometer of FIG. 10, saidolfactometer is described in detail in U.S. Pat. No. 5,118,711 issued onJun. 2, 1992, the specification for which is incorporated by referenceherein.

Referring to FIG. 10, air supply source 3634 provides air to mixingstation 3636 wherein the air is mixed with treatment agent fromtreatment agent source 3635 (source of, for example, the repellent a50-100% geraniol-containing composition or the attractant, lavenderabsolute). The resulting mixture passes through tube 3636g and entersthe apparatus through the side portals. The entry is through a spacerplate and above base plate 3625. The entry of the air-treatment agent isin a direction parallel to the surface of base plate 3625. Thus, thebase plate 3625 is separated from spacer plate 3629 for theair-treatment agent (e.g., the geraniol-containing composition of ourinvention).

Air exits through line 3633a using exhaust fan 3633. The air exit isindicated by reference numeral 3537.

Simultaneously, with the supplying of air and treatment agent frommixing station 3636, light is supplied from beneath the enclosed insectfeeding and/or stimulating means through *light guides 3652, from lightsource 3551 which is powered by electric power supply 3550 marketed byRADIO SHACK® Division of Tandy Corporation of Fort Worth, Tex. 76102under the trademark ARCHER®, Catalog No. 276-228 ("1.0 mm opticalplastic fiber length 5 meter"). An example of light source 3551 isKRATOS Monochromatic Illuminator GM 100 Miniature VIS-IR GratingMonochromator (Model No. GM 100-1, GM 100-2, GM 100-3 or GM 100-4) asmanufactured by KRATOS Analytical Instruments Corporation, 170 WilliamsDrive, Ramsey, N.J. 07446. Another light supply source is the KRATOS GM200 Double Grating Monochromator. Another example of a useful lightsource is the KRATOS GM 252 High Intensity Grating Monochromator. Thebase plate 3625 is also separated from the spacer plate 3629 for thelight guides 3652 whereby the light guides 3652 are held in place in thebase plate 3625 whereby the light (or other forms of radiation) isdirected in a direction perpendicular to the electrical sensor element3610. Air supply source from location 3634 and treatment agent fromlocation 3635 is mixed at mixing station 3636 whereupon treatment agentand air in admixture is passed through lines 3636a and 3636g throughportals located in the spacer element 3628 in a direction along adirectional vector parallel to the electrical sensing element 3610 heldin place by holders 3610a and 3610b. The electrical sensing elements arelocated directly below the horizontally positioned insect feeding and/orstimulating microporous substantially planar lamina 3670 which is heldin place by ring 3660 located on spacer plate 3629 spaced from the baseplate 3625 by spacer ring 3628. It should be noted that the spacer plate3629, spacer ring 3628 and base plate 3625 enclose the entire "enclosedinsect feeding and/or stimulating means" which have controlled limitedaccess to the external environment surrounding the apparatus and inwhich the insects to be tested, e.g., mosquitoes or house flies areplaced.

The insect attractant quantitative detecting means made up of wires 3699(the entire grid being denoted using reference numeral 3610) is locatedimmediately beneath the porous membrane 3670, the outer surface of whichcontains a feeding stimulant composition or stimulant composition forinsects (for example, agar). Immersed in the feeding stimulatecomposition or stimulant composition for insects (e.g., agar) iselectrode 3679 connected to wire 3619 which connects with either wire3619a or 3619b which is connected to the grid wires 3699 (which make upthe insect attractant quantitative detecting means located immediatelybelow lamina 3670).

As stated, supra, the sensor causes an electrical impulse caused by thepressure of the insects landing to proceed through wires 3619a and 3619bto an electrically biased differential amplifier 3639 (using electricalpower supply 3539) also connected to wire 3619c which is connected tothe electrode 3679 which is immersed in the feeding stimulantcomposition or stimulant for the insect and then to a multi-channel A.C.converter 3523. Converter 3523 is associated with program tape storage3524, printer 3520 and data link to digital computer 3521. Differentialamplifer 3639 is connected in series to electrical bias for psuedo host3669 which in turn is connected to wire 3619 which in turn is connectedto the electrode 3679 immersed in the insect stimulant compositionlocated on the surface of porous lamina 3670.

Referring to the testing apparatus, the semiochemical field trap 1000for blood feeding arthopods, field trap 1000 is located in a three-spacewith axes perpendicular to one another. The semiochemical field trap1000 is shown in perspective view in FIG. 21 comprising:

(1) an upright vertically disposed housing;

(2) extending outwardly from the housing a plurality of horizontallydisposed hollow housings 116a and 116b which have contained thereininsect sticky traps;

(3) air 138 and/or carbon dioxide supply means 134, 136 for supplyingair and/or carbon dioxide into the vertical hollow housing and thenthrough the plurality of horizontally disposed hollow housings 116a and116b; and

(4) at least one power supply means for energizing radiation meanslocated on the vertical hollow housing whereby on engagement of thepower supply means with the radiation means and operation of the air 138and/or carbon dioxide supply means 134, 136, arthropods in the vicinityof the trap are attracted by the activated radiation means and the gasemanating from the horizontally disposed hollow housing 116a to alocation so close to the trap 1000 that in the event that an attractingsemiochemical located in the housings 116a and 116b is detected by atleast one of the arthropods, at least one of the arthropods will enterthe inner void of the horizontally disposed hollow housings 116a and116b counter current the gas stream emanating therefrom and remainpermanently entrapped therein.

The semiochemical field trap 1000 of FIG. 21 is disclosed in detail inApplication for U.S. Pat. Ser. No. 887,138 filed on May 22, 1992, thespecification for which is incorporated by reference herein.

A preferred embodiment of our invention comprises anellipsoidally-shaped detergent tablet 830 containing a solid plasticcore 832 which can be fabricated from, for example, polyethylene,polypropylene, nylon, a biodegradable polymer such as poly(epsiloncaprolactone) or any polymer capable of having therein microvoids fromwhich an insect repelling substance, e.g., one of thegeraniol-containing compositions of our invention will be controllablytransported from the plastic core into and through the soap cake over areasonable period of time during the use of the soap cake. Such polymerscan be microporous polymers, such as those described in U.S. Pat. No.4,247,498 issued on Jan. 27, 1981, the specification for which isincorporated herein by reference. Surrounding the central plastic corecontaining insect repellent 832, is detergent 830' which is in the solidphase at ambient conditions, e.g., room temperature and atmosphericpressure. Examples of workable detergents 830' are "elastic" detergentssuch as those described in U.S. Pat. No. 4,181,632 issued on Jan. 1,1980, the disclosure of which is incorporated herein by reference, or"transparent" soaps such as those set forth in U.S. Pat. No. 4,165,293issued on Aug. 21, 1979, the disclosure of which is incorporated hereinby reference. Other examples of the detergent 830' useful in ourinvention are those set forth as "variegated soaps" in Canadian LettersPatent No. 1,101,165 issued on May 19, 1981.

On use of the soap tablet 830 or detergent bar, the insect repellentagent originally located in plastic core 832 is transported at a steadystate from core 832 through core surface 831 through the detergent 830'and finally through the surface of the detergent bar at, for example,833, 834, 835 and 836.

The detergent bar or tablet 830 of our invention may be of any geometricshape, for example, a rectangular parallelepiped tablet as is shown inFIGS. 15, 16 and 17 containing solid plastic core 839. The insectrepellent located in solid plastic core 839 on use of the detergent barpasses through at steady state, surface 837 of FIG. 16, detergent 838and finally surface 839 at, for example, locations 840, 841, 842 and843. The environment surrounding the detergent bar on use thereof isthen treated with the insect repellent at 843, 844 and 845, for example.Optionally, aromatizing agent can also be contained in the detergent bar(if desired) and so the environment surrounding the detergent bar on usethereof would also be aesthetically aromatized at 843, 844 and 845, forexample if the geraniol-containing composition of our invention isinsufficient for such aromatization. In certain instances suchgeraniol-containing compositions are indeed sufficient for sucharomatization.

As is shown in FIGS. 18, 19 and 20 the plastic core of the detergenttablet 830 may have a single finite void at its center 851 (of FIGS. 19and 20) in which the insect repellent agent and optionally anyadditional aromatizing agents are contained. The plastic core is a shell848 having outer surface 852 (shown in FIGS. 19 and 20). The insectrepellent agent (and optionally any additional aromatizing agent)contained in the void in the plastic core permeates through shell 848,past surfce 852 at a steady state, through the detergent 847 and to theenvironment at, for example, 856, 857 858 and 859.

In addition to the insect repellent contained in the core, e.g., core839 or core void the core can also contain other materials fortherapeutic use, for example, bacteriastats, deodorizing agents and thelike which are compatible with the geraniol-containing compositions ofour invention. In the alternative, the plastic core of the detergenttablet of FIGS. 18, 19 and 20 may have an empty single finite void atits center 851 with the insect repellent contained in the shell 848.

At the end of the use of the detergent tablet, the hollow core or thesolid core can be used as an insect imparting and aroma imparting or airfreshener household article. In addition, depending on the ratio of thevolume of the void 851, to the solid part of the detergent table ofFIGS. 18, 19 and 20, the detergent tablet of FIGS. 18, 19 and 20 can beso fabricated that it will float on the surface of the liquid in whichit is being used and this physical attribute has certain obviousadvantages.

The foregoing mixture is placed in an autoclave and intimately admixedwith a perfuming-insect repellent composition containing 95% by weightof geraniol and 5% by weight nerol of the total candle base composition.

The autoclave is sealed and heated to 180° C. under 15 atmospherespressure and maintained with vigorous shaking for a period of fivehours. At the end of the five hour period, the autoclave isdepressurized (being under a nitrogen pressure atmosphere) and theautoclave is opened and the contents are then poured into cylindricalcandle molds 4" in height and 2" in diameter containing 0.125" wicks.The resulting candles have efficacious mosquito and house flyrepellencies and have aesthetically pleasing aromas on use.

The candles are effective in preventing house flies and mosquitoes fromentering a room in which two candles have been burning for 15 minutes,the said room having dimensions of 6'×15'×15' and having a 3'×3' openportal adjacent to fly and mosquito-infested region in the month ofAugust, 11988 in the temperate zone of Highlands, N.J. adjacent RaritanBay.

EXAMPLE II

A study was conducted to evaluate the efficacy of candles which aredesignated as "A", "B" and "C" in repelling house flies (Musca domesticaL.(Diptera:Muscidae)).

Candle "A" contained 95% Paraffin Wax and 5% of 100% geraniol.

Candle "B" contained 90% Paraffin Wax and 10% citronellol oil.

Candle "C" contained only Paraffin Wax.

The candles are allowed to burn for 20 minutes and the number of houseflies and mosquitoes repelled is recorded for the next 60 minutes withthe following equipment and procedure:

Materials Test Chamber

The evaluation was conducted in a 28.3 cubic meter chamber with airingports. A screened cage measuring 15 cm×15 cm×47.5 cm was attached insidean upper airing port, and a screened repellency observation cagemeasuring 15 cm×15 cm×32.5 cm was attached outside the upper airingport. The two cages were held together by a Masonite plate which fitfirmly in the airing port. A 4-cm hole located in the center of eachMasonite plate provided an escape for the test insects. A barrier wasused to close the hole.

Attractant

A caged mouse was used as an attractant and was placed inside thechamber in the larger section of the repellency cage.

Test Insect

Adult House Flies (Musca domestica L.(Diptera:Muscidae)) are TestInsects.

Procedure

For each replicate, 75 to 100 adult house flies were removed from therearing cage by means of a vacuum aspirator, and transferred by carbondioxide anesthesia to the inner cage containing the mouse. The assembledcage was placed in one of the upper ventilation ports of the chamber.For each experimental situation the test insects were transferred to aclean cage containing the mouse. A house fly candle was placed centrallyon the chamber floor and burned for 20 minutes before initiating therepellency counts. The maximum period for the repellency counts was 60minutes. The first repellency count was made at 10 minutes after theburning ended, and subsequent counts were taken at 5-minute intervalsthereafter. The number of house flies repelled were those escaping tothe outside cage. For the control, counts were made in a similar manner,but no candle was burned.

The same three candles were used for all four replicates. Betweenreplicates the chamber was exhausted, the Kraft paper * flooring for thechamber was replaced, and the two screened repellency cages weresubmerged in hot detergent water, rinsed and dried.

Results

The overall average percent of house flies repelled for each candle for60 minutes was as follows:

Candle "A"--94%

Candle "B"--53%

Candle "C"--16%.
